(*1) This pin can only be used as ADC input, cannot use it as normal I/O. when not using,
just connect nothing. When used as ADC input, the input voltage range is 0~1.0V.
(*2) UART0 is serial port, during power on progress; this serial port will output something,
which can be ignored.

5. Antenna Information
5.1 Antenna Type
Antenna can be connected only using On-board PCB antenna.
5.2 Reduce Antenna Interference
While using the On-board PCBantenna, in order to have the best Wi-Fi performance, it’s
recommended to keep a minimum15mm distance between the antenna part and the other metal
pieces.
User’s own PCBA design is recommended NOT to pass any wire, NOT do copper pour under
the region of the module’s antenna, to avoid interferences.

6.3 Production Guide

The storage for the delivered module should meet the following condition:
1. The anti-moisture bag should be kept in the environment withtemperature< 30℃ and
humidity< 85% RH.
2. The expiration date is 6 months since the dry packaging products was sealed.
 Cautions:
1. All the operators should wear electrostatic ringin the whole process of production.
2. While operating, water and dirt should not have any contact with the modules.
